Journal ArticleDOI
A novel avian hypothalamic peptide inhibiting gonadotropin release.
Kazuyoshi Tsutsui,Etsuko Saigoh,Kazuyoshi Ukena,Hitoshi Teranishi,Yuko Fujisawa,Motoshi Kikuchi,Susumu Ishii,Peter J. Sharp +7 more
TL;DR: It is shown, in a bird, that the hypothalamus also contains a novel peptide which inhibits gonadotropin release, the first hypothalamic peptide inhibiting gonadotropic hormone reported in a vertebrate.
Journal ArticleDOI
The adrenocortical response of tufted puffin chicks to nutritional deficits.
TL;DR: The hypothesis that puffin chicks suppress HPA-axis activity in response to short- and long-term nutritional deficits may allow a chick to extend its development in the nest, while eluding detrimental effects of chronic cort elevation.
Journal ArticleDOI
Reproductive development according to elevation in a seasonally breeding male songbird.
Nicole Perfito,Nicole Perfito,Anthony D. Tramontin,Simone Meddle,Peter J. Sharp,Daniel Afik,Jennifer M. Gee,Susumu Ishii,Motoshi Kikuchi,John C. Wingfield +9 more
TL;DR: In this article, the authors demonstrate variation in reproductive timing across small geographic distances by examining the vernal testicular recrudescence of adult song sparrows (Melospiza melodia morphna) breeding in coastal and montane habitats.
Journal ArticleDOI
Living-cell imaging of transgenic rat anterior pituitary cells in primary culture reveals novel characteristics of folliculo-stellate cells
Kotaro Horiguchi,Motoshi Kikuchi,Kenji Kusumoto,Ken Fujiwara,Tom Kouki,Kotaro Kawanishi,Takashi Yashiro +6 more
TL;DR: The novel characteristics of FS cells observed in the present study suggest that in the anterior pituitary gland, FS cells play important roles in determining and/or maintaining local cellular arrangement in the presence of ECM components.
Journal ArticleDOI
Expression of Chemokine CXCL12 and Its Receptor CXCR4 in Folliculostellate (FS) Cells of the Rat Anterior Pituitary Gland: The CXCL12/CXCR4 Axis Induces Interconnection of FS Cells
Kotaro Horiguchi,Cimi Ilmiawati,Ken Fujiwara,Takehiro Tsukada,Motoshi Kikuchi,Takashi Yashiro +5 more
TL;DR: This study attempted to discover the factor that induces interconnection of FS cells and succeeded in identifying chemokine (CXC)-L12 and its receptor CXCR4 as potential candidate molecules.
